QuliMetal Stainless 17.5" Flavorizer Bars & Heat Deflectors for Weber Genesis 300 — 5-Pack + 2 Deflectors, 16‑Gauge Corrosion-Resi

These QuliMetal stainless-steel 17.5" flavorizer bars and matching heat deflectors replace worn porcelain parts on Weber Genesis 300 series grills for longer life, better corrosion resistance, and easier cleaning.

If your Weber Genesis 300 series grill is showing chipped enamel, rust, or uneven heat because the original porcelain-coated flavorizer bars or thin heat deflectors have deteriorated, this QuliMetal kit is a direct-fit stainless upgrade. The set contains five 17.5" flavorizer bars and two stainless heat deflectors sized for front-control Weber Genesis E/S/EP/CEP-310/320/330 models (note: it does not fit the Genesis II 300 or Genesis II LX 300 series). Built from heavier 16-gauge stainless steel, these parts are designed to resist chipping, flaking and corrosion that commonly affect porcelain-coated replacements.

How do these stainless flavorizer bars improve grill durability?

The QuliMetal bars are made from solid 16GA stainless steel, noticeably thicker than many aftermarket options. Because they are non-magnetic stainless, they won’t rely on a fragile porcelain coating that can crack and expose steel to rust. Expect longer service life and fewer replacements.

• Material: 16-gauge heavy-duty non-magnetic stainless steel
• Weight: kit totals approximately 9.8 lbs for a sturdier feel
• Corrosion resistance: solid stainless avoids flaking enamel

Will these parts fit my Weber Genesis 300 series grill?

This QuliMetal kit is cut to match Weber Genesis models with front-mounted control knobs: E-310, E-320, E-330; S-310, S-320, S-330; EP/CEP-310, EP/CEP-320, EP/CEP-330. Measure before ordering if you’re unsure; the kit does not work with Genesis II 300 or Genesis II LX 300 series models.

• Flavorizer bars: 17.5 x 2.25 x 2.375 inches each
• Heat deflectors: 13.25 x 8.75 inches each
• Included: 5 stainless flavorizer bars and 2 stainless heat deflectors

How will these replacements affect cooking and maintenance?

Stainless flavorizer bars vaporize drippings to add sear and flavor while directing heat evenly across the burners. Because they won’t chip or peel like enameled parts, cleaning is simpler—wipe or brush off grease and they stay intact season after season. Their greater mass also helps stabilize temperature variations.

• Flavor enhancement: effective vaporization of drippings
• Cleaning: easy to scrub or hose down without coating loss
• Heat distribution: heavier bars reduce hot/cold spots

What are the key differences versus porcelain-coated replacements?

Porcelain-coated components can crack, revealing underlying steel that rusts and disintegrates over time. QuliMetal’s all-stainless construction eliminates the plated layer, removing the failure point and delivering long-term structural integrity under high heat and outdoor exposure.

• No plating to chip: solid stainless construction
• Better longevity: resists corrosion and high-heat wear
• Consistent performance: maintains shape and coverage over time

Who is this for: Grill owners who want a robust, long-lasting replacement for failing or fragile Weber Genesis 300 series porcelain flavorizer bars and heat deflectors. Ideal for frequent grillers, those who store grills outdoors, or anyone wanting a maintenance-friendly upgrade that restores even heating and reduces future part replacements. Confirm your grill model (front-mounted knobs Genesis E/S/EP/CEP-310/320/330 series) before purchasing.
